The flag has a typo in it, it's "...-than=..." and not "...-then=...",
so this was in fact never used. Since we're also using -Wvla (without
size), we should already get warnings about any variable length arrays
anyway, so the additional "-Wvla-larger-than" does not make much sense
and thus we can simply drop this.

Currently `virt-host-validate` will fail whenever one of its calls fail,
regardless of virHostValidateLevel set.
This behaviour is not optimal and makes it not exactly reliable as a
command line tool as other tools or scripts using it would have to check
its output to figure out whether something really failed or if a warning
was mistakenly treated as failure.
With this change, the behaviour of whether to fail or not, is defined by
the caller of those functions, based on the virHostValidateLevel passed
to them.

Currently we expose libvirt Go packages at
libvirt.org/libvirt-go
libvirt.org/libvirt-go-xml
These packages have not supported Go modules historically and when we
tried to introduce modules, we hit the problem that we're not using
semver for versioning.
The only way around this is to introduce new packages under a different
namespace, that will have the exact same code, but be tagged with a
different version numbering scheme.
This change proposes:
libvirt.org/go/libvirt
libvirt.org/go/libvirtxml
Note the hyphen is removed so that the import basename matches the
Go package name.

Cloud-Hypervisor is a KVM virtualization using hypervisor. It
functions similarly to qemu and the libvirt Cloud-Hypervisor driver
uses a very similar structure to the libvirt driver.
The biggest difference from the libvirt perspective is that the
"monitor" socket is seperated into two sockets one that commands are
issued to and one that events are notified from. The current
implementation only uses the command socket (running over a REST API
with json encoded data) with future changes to add support for the
event socket (to better handle shutdowns from inside the VM).
This patch adds support for the following initial VM actions using the
Cloud-Hypervsior API:
* vm.create
* vm.delete
* vm.boot
* vm.shutdown
* vm.reboot
* vm.pause
* vm.resume
To use the Cloud-Hypervisor driver, the v15.0 release of
Cloud-Hypervisor is required to be installed.
Some additional notes:
* The curl handle is persistent but not useful to detect ch process
shutdown/crash (a future patch will address this shortcoming)
* On a 64-bit host Cloud-Hypervisor needs to support PVH and so can
emulate 32-bit mode but it isn't fully tested (a 64-bit kernel and
32-bit userspace is fine, a 32-bit kernel isn't validated)

Some of our really old APIs are missing @flags argument. We
introduced their variants with "Flags" suffix and wired some
logic into virsh to call the new variant only if necessary. This
enables virsh to talk to older daemon which may be lacking new
APIs.
However, in case of cmdSetmem() we are talking about v0.1.1
(virDomainSetMemory()) vs. v0.9.0 (virDomainSetMemoryFlags()) and
in case of cmdSetmaxmem() we are talking about v0.0.3
(virDomainSetMaxMemory()) vs v0.9.0 (virDomainSetMemoryFlags()).
Libvirt v0.9.0 was released more than 10 years ago and recently
we dropped support for RHEL-7 which has v4.5.0 (released ~3 years
ago). Thus it is not really necessary to have support in virsh
for such old daemons.

When processing node devices, the udevProcessStorage() will be
called if the device is some form of storage. In here, ID_TYPE
attribute is queried and depending on its value one of more
specialized helper functions is called. For instance, for
ID_TYPE=="cd" the udevProcessCDROM() is called, for
ID_TYPE=="disk" the udevProcessDisk() is called, and so on.
But there's a problem with ID_TYPE and its values. Coming from
udev, we are not guaranteed that ID_TYPE will contain "cd" for
CDROM devices. In fact, there's a rule installed by sg3_utils
that will overwrite ID_TYPE to "cd/dvd" leaving us with an
unhandled type. Fortunately, this was fixed in their upstream,
but there are still versions out there, on OS platforms that we
aim to support that contain the problematic rule. Therefore, we
should accept both strings.
